Report this item

This two piece pin set is a bit different from our other receiver pins. It has a small detent inside the larger pin where the ball bearing on the smaller pin locks into place. It offers a solid lock and will secure the upper and lower during even the harshest mag dumps. Fits all Master Piece Arms 9mm, mid size and Mini 930.
